. IMPROVEMENT IN MACHINES FOR MAKING MACHINERY K -zvs.

Specification forming'part of Letters Patent No. l86,439, dated January 23, 1877; application filed June 19, 1876.

To all whom it-may concern:

Be it known that I, ANDREW SHoeREN, of Sandwich, in the county of DeKalb and State of Illinois, have invented a new and useful Improvement in Machines for Making Machinery Keys, which is fully described in the following specification, reference being had to the accompanying drawings, in which-9 Figure 1 represents a perspective view of the machine, Fig. 2, a side elevation of the same Fig. 3, a longitudinal vertical section of the machine, as shownin Fig. 2; Fig. 4, a transverse vertical section, taken on the line a? w, Fig. 2; Fig. 5', a detail plan view of the beater or swaging-cylinders; Figs. 6 and 7, detail views of the devices for adjusting the horizontal swaging-cylinder so as to taper the key; Fig. 8, a perspective view of the devices for holding the bar on the sliding table, and also'the gage-plate; Fig. 9, a perspective view of the device for stopping and holding the sliding feed-table when it is drawn back,and Figs. 10 and. 11 detail views of devices for stopping and starting the gearing by means of l which the reciprocating table isdrawn back.

My invention relates to a machine for rolling or forging crow bars with either atrue or an irregular taper, as may be desired, and particularly designed for the manufacture of keys for machinery. 1 i l The invention consists in supporting. the horizontal beating-cylinderin a pivoted frame, so that it can be adjusted vertically to taper the rod as it is swaged. It also consists in the combination, with said pivoted frame, of a lever, provided with an inclined 1 guideway, by means of which the necessary adjustment of the frame is eflected to taper the forged bar. It also consists in the combination of this actuatinglever with the feed plate, so that the lever is operated by the reciprocation of the latter. It also consists in making said actuating-lever jointed and adjustable, so that the inclination-pitch of the taper may be adjusted at will. it also consists in attaching the beating rollers'on the vertical cylinders by means of swagingplates or arms, so that this distance between the rollers may be adjusted and the latter may be readily removed. And it further consists in various devicesand combinations of devices having certain subordinate functions in the operation of the machine, as will be hereinafter fully described and set forth.

In the drawings, A represents the main or supporting frame of the machine, which may be of any suitable construction, for receiving the different parts of the machine and holding them in place. A frame, B, is pivoted to suitable lugs or arms a, on one end of the main frame, and in this. pivoted frame is mounted a horizontal shaft, 0, which carries a beating or swaging cylinder, 0,: provided with a roller, 0 This cylinder is driven from the main driving-shaft D,through an upright shaft, D, by means of a bevel-gear, d, on the shaft D meshing-with a corresponding wheel, al on the lower end of the shaft D-,and a bevelrgear, d on the upper end of the shaft 1), which meshes with a corresponding gear, 0 on one end of the shaft O. The wheeld is loose upon the shaft D, so that it can slide thereon, and the latter is supported at its upper end in a bearing, b, which is rigidly connected to one arm of the frame B. The bearing b being below the wheel d whenever the frame B is raised or lowered, the wheels 0 and d are kept in gear, so that the rotation of the shaft 0 is not interrupted. Just below the shaft 0, two upright shafts, E E, are mounted in the main frame, which are driven by bevel-gear wheels e e on the. lower ends, meshing with correspondifig' wheels 01 on the main driving-shaft. j v 7 On the upper ends of the shafts EE are mounted disks E, which carry heating or swaging rollers e, which are supported by hearings in swinging frames 6 pivoted to the disks E, as shown in Fig. 5 of the drawings, and are free to swing back and forth on their pivots. The disks E are recessed, as shown in Fig. 5 ofthe drawings, to accommodate the rollers 'c ,.and also to provide. a support for a set-screw, c, by means of which the swaging-frarnese may be adjusted so as to regulate the distancebetween the rollers 0 By mountingthe rollers in frames pivoted to the disks, I am also enabled to readily replace either of these devices whenever it becomes necessary. On the main frame, arranged just below the opening between the disks E, is a forked or branching, so as top-ass around the shafts E, to be attached at the extreme rear end of the 'main frame. A swinging arm,f,

.depends from thelever F, and is pivoted to a crossbar, F near the bottom 6f the frame, from each end of which an arm, f, extends upward, and is pivoted to the forward ends of the arms of the swinging frame B.

It is evident, therefore, that by vibrating the lever F the frame B will be correspondingly moved, thereby raising and lowering the horizontal beating or forging cylinder. To accomplish this the forward or free end of the lever F is provided with an inclined slot, f in which astud or pin is made to move horizontally, thus raising and lowering the forward end of the lever as it moves back and forth.

The lever F may be made in one piece; but I prefer to construct it in two parts, the forward piece F being pivoted to the rear portion, so as to be adjusted in relation thereto.

1 A clasp or loop,f is pivoted to a pendant on the rear section of the lever, and is made to embrace a similar pendant on the rear end of the front section of the same. In the end of'this loop is a set-screwJ", and in the lower end of the rear pendant is another set-screw, f which passes through and works against the pendant on the front section of the lever. It is evident that by adjusting this attachment by means of the set-screws the relation of the front section F to the rear section of the lever F will be changed, thereby changing the inclination of the slotf making its pitch greater or less, as may be desired.

A feed-table, G, is mounted upon suitable ways'on the main frame, so as to slide back and forth thereon freely. Upon the lower side of this table is a slotted pendant, g, and in the slot is fixed a pin or stud, 9 which is inserted in the inclined slot, f, in the lever F, and is made to move back and forth therein-by the reciprocation of the feed-table G. The pin 9 is adjustable vertically in the pendant, so as to accommodate the adjustment of the lever-section F drawn forward toward the forging-cylinders by a weight, H, attached to a cord or chain, It, running over a pulley, h, at the rear of the machine, and extending forward and attached to the table. The table is drawn back from the cylinders by means of a pinion, i, which engages with a rack, 9 ,011 the under side of the feed-table. The pinion i is on a shaft, t", on one end of which is loosely mounted a gear-wheel, I, meshing with apinion on a shaft, 1, which is driven from th main driving-shaft D.

On the shaft 1" is a sliding clutch, i which is moved back and forth to engage with and disengage from clutch-teeth on the. hub of The feed -'table is the wheel I, so as to produce an intermittent rotation of the shaft i and pinion t.

A bell-crank lever, J, is pivoted to a support on the main frame, and has its outer end forked so as to embrace the clutch t in a groove thereon. Asliding rod, j, is attached to the other end of the lever J, and extends to the front end of the machine, in the end piece of which it is loosely supported. An eye, jl, depending from the forward end of the feed-table embraces the rod j, and on the rod are stops j against which the eye strikes as the table is reciprocated, the stops being arranged so that'when the table is thrust forward toward the forging-cylinders the wheel I is clutched to its shaft, so that the backward motion of the table is commenced immediately, and continued until the table reaches the front end of the machine, when the pendantj striking against the front stop j, pulls forward the rod J, disengages the clutch t and the table stops.

The front stop j is adjustable on the rod J, and behind the corresponding rear stop is placed a cushioning-spring, j A holdingspring, j, attached to the bottom of the feedtable, rests against the inner end of the clutchlever J On the feed-table G is a rest or support, K, for the bar, just above which is suspended a swinging cam, 70, pivoted to a post, 70 attached to the feed-table. .On the table G is also a pivoted lever, K, the outer end of which is bent to form a handle, while the inner end is bent in the opposite direction,.and is attached ,by a li'nk,'k ,to a projection on the cam It.

It will thus be seen that by moving the lever K, the cam 70 is oscillated upon its pivot,

so as to gripe the bar between its face and the rest K, or release the bar from this holdingdevice at pleasure.

A stop-spring, L, is attached to the main frame of the machine, and is provided with a stud or stop, l, which projects up through a slot in the face of the frame. On the table G is a projecting arm, l, which extends out beyond the table at one side, so as to depress the spring L when it comes in contact with the stop 1 on the backward movement of the feed-table, until it passes said stop, when the latter is immediately forced up by the spring in front of the arm 1 and holds the feed-tab'le from forward movement by the action of the weight H.

On the'free end of the spring L is a key, 1 which extends up through the frame-plate,"so that by depressing it the arm l is released, and the feed-table is free to move forward.

The pendant f is hungnpon an eccentric pin, M, journaled in the lever F, and upon one end of the pin is a crank-arm, m, rigidly attached thereto. A rod, M, is attached to this crank-arm, and extends to the frontend of the-machine, being supported loosely in a hanger, W, on the under side of the foodtable, so that the hanger slips along over the throwing the eccentric back, so as to lower the vibrating frameto a working position; A

' bar, N, is pivoted to thecross-piece F and extends upward between the two branches of the lever F, near a stop, a, thereon. Behind thisbar is a pressure-spring, n which forces the bar N up against the stop n. The upper end of the bar N is notched, and when the cross-bar F is raised by the eccentric M, as 'heretofore described, the notch it? engages with the stop a so that the cross-bar and horizontal beater-shaft are held in an elevated position. A short stud, n projecting from the rear end of the feed-table, strikes against the upper projecting end of the arm N, when the table is pulled forward to the forging-cylinders, disengages it from the stop n, and the cross-bar F drops from the weight of the frame upon it, the eccentric M being so arranged that it is never turned up so as to stand upon a dead-center by the drawing forward of the rod M, as described.

This arrangement of the eccentric, and other devices connected therewith, is clearly shown in Figs. 6 and 7 of the drawings, in which the former represents the crossbar and forging shaft in an elevated position, and the latter the same position in dotted lines, and the working position after the rolling frame has been allowed to drop in full lines.

A pin, or, on the lever F stops the backward movement of the crank-arm m, thereby preventing the turning of the eccentricso as to permit the cross-bar F to fall below a certain fixed position. A rock-shaft, O, is supported in standards 0, placed on the main frame by the side of the way, along which the feed-table moves. These arms are bent, as shown in the drawings, so as to bring the rock-shaft over the feed-table. A small bent rod, 0, is attached to the rock-shaft 0 so as to be parallel with it, and under this rod the inner bent end of the rocking lever K passes, so that when said lever is rocked so as to turn down the cam k, the rod 0 is thrown up, and vice versa. On the-end of the rock-shaft O, nearest the forging-cylinders, is agage-arm,

O, which vibrates up and down when the necting the blade P with a crank-wheel, Q,

on a shaft, q, driven by a suitable gearing from the shaft I. A driving-pulley is mounted upon the main driving-shaft D, by means of Which motion is communicated by any suitable mechanism to the machine, or the shaft D may be driven in any other suitable manner.

; Theoperation of my machine is as follows: The feed-table being drawn back to the forof the drawings, and the horizontal forgingcylinder will be raisedso high above the anvil that the rod or bar from which the keys are to be forged can be thrust in underneath the cylinder without difficulty. The bar S is then placedupon the teed-table, thrust forward to the gage O, which is turned down in. front of the anvil, and secured in position by turning the clamp K down upon it, which, at the same time, raises the gage out of the way. The feed-table is then released by depressing the stop-spring L, and is suddenly pulled for: ward by the weight H, carrying the bar S onto the anvil a, underneath the cylinder 0, and

between the disks E". At the proper moment.

the stud a releases the arm N from the stop n, and the forging=cylinder 0 drops down into working position. Simultaneously the wheel I is clutched to the shaft 0' by the mechanism described above, and the feed-table G commences to move backward, drawing back with it the bar S, which is forged into the desired shape as it is drawn back by the operation of the revolving beater-rollers c and 0 As the pin on the feed-table moves backin the inclined slot in the lever F, the horizontal forging-shaft is gradually depressed, so that the key will be beaten out or forged witha taper. When the table is moved to the extreme forward end of the machine and stopped, as heretofore described, the bar is released and moved to the shears at one side of the frame, the key is cutoff, the bar is again secured in position, and the foregoing operation is repeated.

By adjusting the stud or pin in the pendant g, and by adjusting the pivoted slotted section of the lever F, the inclination of the taper is varied.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the pivoted frame B and horizontal forging cylinder mounted thereon, substantially as and for the purpose set forth.
